The screen shot below is from a live QlikView application we ran during the QlikView 2012 Event in Miami which tracked all Tweets containing the hashtag #qonnections.

The application also scored these Tweets for sentiment, extracted keywords and looked up the Klout score for all the Tweeters.

The application was built in just 2 hours as explained in this blog post.

We also ran a similar dashboard for the Business Discovery World Tour event in Eindhoven which you can download here.
